MAIL-BAG LOCK.

SPECIFICATION forming part of Letters Patent No. 351,063, dated October19, 1886.

I Application filed April 26, 1886. Serial No. 200,169. (X model.)

To aZZ whom it may concern:

Be it known that I, JOHN HOWARD Mo- CORMICK, a citizen of the UnitedStates of America, residing at New Orleans, in the parish of Orleans andState of Louisiana, have invented certain new and useful Improvements inMail-Bag Locks, of which the following is a specification, referencebeing had therein to the accompanying drawings.

My invention relates to mail-bag locks; and it consists in a lock orfastener for the cords of inail-bags, the peculiar features of whichwill be fully understood from. the following description, when taken inconnection with the i annexed drawings.

Figure 1 is a perspective view of my improved lock, showing a cordapplied to it. Fig. 2 is a longitudinal central section of the lock,showing a cord gripped in it by one of the levers or-dogs. Fig. 3 isatop view showing the interior of the lock case. Fig. I is a view of thekey. Fig. 5 shows the device ap plied to a bag.

-eferring to the annexed drawings by lettcrs, A designates the case ofthe lock, which is preferal ly.reetangular and constructed with apillow, G, leaving a depression, a. Itis also constructed with areceptacle, It, adapted to receive and hold a tag or card, S.

E E designate two curved gripping dogs or levers, which are free to rockon a transverse fulcrum-pin, A, and which are curved somewhat resemblingthe italic letter-f. Directly over t he flat surface ofthe pillow G theenlarged 5 gripping ends 01' the lovers are serrated, as indicated at I,and at the opposite depressed ends of these levers are slight roundedlugs or wards K K. In the same planes with and near the lugs or wards KK are studs F F,

fixed to the levers. The object of the studs and wards above describedis to allow the notched bit of the key I to pass them in the act ofunlocking or freeing the cord or rope M from the gripping ends of thelevers K K.

B designates the keyhole through one side 5 of the lockrase, directlyopposite which is a cupped key-barrel seat, H.

The stepped cone L (shown in Fig. 3) is designed to receive the stepsshown on the key in Fig. I.

By reference to Fig. 2 it will be seen that the cord or rope M is passedthrough apertures O,beneath the long arms of levers K,between theserrated gripping ends of said levers and the pillow G, and out of thecase through apertures O. The cord is thus bent or deflected out ofastraight line in its course through the lock-case.

I am aware that serrated gripping dogs or levers, in combination withcases, have been used before my invention for mailbag-rope fasteners,and I do not tl'lerefore claim such devices, broadly.

IVhat I do claim as new is 1. A mail-bag lock consisting of a casehavinga pillow, G, and a depression, a, a keyhole, and perforations for thepassage of a cord, in combination with curved levers provided withserrations, substantially as described.

2. The combination, in a mail-bag lock, of 7c the case A, constructedwith a tag-receptacle,

a pillow, G, a depression, a, a key-hole and keybarrel cup,gripping-levers E E, fulcrumed at A, and provided with wards K K, studsF F, and serrated gripping ends, and the cord-apertures through the endsof the case, all constructed and adapted to operate substantially in themanner and for the purposes described.

In testimony whereof I aifix my signature in presence of two witnesses.
